Managing virtual storage for subprograms - changing PL/I application programs

AR/CTL provides the Subprogram Virtual Storage (ARCSPVS) application program interface (API) for managing defined areas of virtual storage for any application program, including a subprogram, in a restartable environment.

If an application subprogram already uses the subprogram support that is provided with the QUICKSTART for MVS product, no program changes are required for the use of AR/CTL support for subprograms. For more information, see QUICKSTART-to-AR/CTL bridge.

The following sections explain how to implement the ARCSPVS API in a PL/I application program.

For background information, see Overview of the ARCSPVS API.
